Answer:

See explanation

Explanation:

In order to answer this question, we have to look at the principle of conservation of mass. This principle states mass is neither created nor destroyed in a chemical reaction.

Hence, in a chemical system undergoing a reaction, the total number of atoms present in the system remain the same before and after the reaction. This also implies that the weight of the system does not change.

Thus, the weight of a chemical system does not change after a chemical reaction.

Read this information about environmental scientists and chemists. Which statement accurately describes a way in which the jobs
Gennadij [26K]

Answer:

Environmental scientists look for solutions to protect the environment, while chemists develop new products.

Explanation:

The last two sentences use the conjunction while meaning <em>whereas</em>, i.e. indicating a contrast. So the purpose of sentences 3 and 4 is to contrast certain things about environmental scientists and chemists. However, the fourth sentence contrasts only <u>level of education</u> required for these jobs.

The third sentence refers to <u>actual</u> <u>work</u> that environmental scientists and chemists do. Therefore, this sentence most accurately describes a way in which the jobs of environmental scientists and chemists contrast.
